Application led January 9, 1930. Serial No. 419,551.`

My present invention relates to cop holders for braiding machines and the like; one object of my invention is to provide an improved locking structure for the ratchet head and the central tube of the cop holder.

Another object is to provide a locking structure which will prevent relative turning of the parts.

A further object is to provide an improved outer sleeve construction having great resiliency and holding power.

Vith these and other objects and advantageous features in view, the invention consists of novel arrangements of parts more l5 fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more particularly set forth in the appended claims.

In the drawings:

Fig. 1 is an elevation of the improved cop holder;

Fig. 2 is an elevation of the base thereof;

Fig. 3 is an elevation of the outer sleeve;

Fig. 4 is a section on the line Li--l of Fig- '25 ure 3;

Fig. 5 isa central section of the assembled base- Fig. 6 is a` view showing the parts thereof prior to assembly; 3 Fig. 7 is a section on the line 7-7 of Figure 5; and

Fig. 8 is a bottom plan view of the ratchet head.

It has been found desirable in the construction of metal cop holders, to mechanically lock the central tube thereof to a metal ratchet head so as to prevent relative turning, and Vto secure an outer sleeve to the central tube which has increased resilience and exerts a greater resistance to slipping of the yarn cop thereon. A

I have therefore provided a cast metal ratchet head with a central opening having an annular upstanding hub, said hub having therein; and I have positioned a central tube having an annular flange provided with spaced lateral displaced portions which form radial keys, in the ratchet head opening so as to seat the radial 5-9` keys in the spaced slots or recesses of the hub,

they end of .the tube passing through the ratchet head opening and being turned over the edge thereofto lock the parts together.

Onthe centra having two c lindrical end sections which embrace; the tu ltube is welded an outer sleeve e, and an intermediate section formedof; spaced resilient strips integral with the end sections and in arched relation bathe .central tube, each strip'being laterally displaced in fthe-same direction so that the frictional resistance to turning tendsAv to shift thestripsbackand thus increases the engaging. force;.and following herewith is adetailed description of aspecific cop holder embodyingthe structural and otherfeatures of my invention. j

. Referring to the drawings, the ratchet head 10 is preferably of cast metal, and has the usual ratchet cular opening teeth` 11 thereon; a central cir- 12 .is provided, and an upstandinghub 13 surrounds the opening and has spacedslotsorrecesses 14 in the upper thereof..

HA central tube 15,

end

lpreferably formed of sheet metal, hasan annular 'flange 16 formed adjacent the lower edge thereof, as by upsetting, this .flange having laterally displaced portions 17' on the lower edge thereof which serveas radial keys adapted to seat within the corresponding recesses 14:;of the hub.

`In ,assembling the tube andthe ratchet head,

the 'lower end ofthe tube is `passed through the, ycent-ral opening 12, the keys 17 seating within the recesses V14 and the end 18 is then turnedover the lower edge .of the central Opening,

as shown in Figure `7, to lock the two parts in .assembledV position. r Referring no w toFigure 3, an outer sleeve two'.L cylindrical Vmediate section preferably of sheet metal, with kend sections 2O and an inter- 21V having spaced strips 22,

theseEstrips being integral with the end sectiens and-generally wthgthe fOimCled U-shaped in cross section portions outward, each member being arched aslshown in Figurel, and then displaced laterallyl `in a clockwise direction, as seen from the ratchet head. This displacement strip, cop, hOldi therefore ,similar foreach the direction of pull on the has tending t0 .-'Sbift ,the YdiS- placed parts back on increase of resistance; this shifting tends to increase the arching of the strips, and therefore increases the gripping force.

The outer sleeve is positioned on the central tube, and the end sections are then welded or otherwise secured to the tube, the members 22 thereuponA functioning as resili ent cop holding members the lateral displace,- ment thereof increases the length of resilient cop engaging surface and resists slipping both on account oi' the arcuate engaging area and the tendency to increase the radial displacement of the strips upon excessive resistance to turning.

My improved cop holder is simple to construct and to assemble, has increased rigidity, increased holding power, and better resists slipping. IVhile I have described a specific construction embodying' the features of my invention, it is obvious that desired changes in assembly or arrangement may be made to suit particular cop holder requirements, within the spirit and the scope of the invention as defined in the appended claims.

I claim:

l. In a cop holder, a metal ratchet head having a central opening, a central tube positioned in said opening, and a flange integral with said tube seated on one side of the opening, the end of the tube being turned over the edge of the other side of the opening.

2. Ina cop holder, a metal ratchet head having a central opening, a hub around said opening, a central tube positioned in said opening, an integral fiange thereon seated on the hub at one side of the opening, the end of the tube being turned over the edge of the other side of the opening, and cooperating locking means on said flange. and hub for preventing relative rotation thereof.

3. In a cop holder, a metal ratchet head having a central opening, a hub around said opening, said fiange having spaced recesses therein, a central tube positioned in said opening, an integral flange thereon, and spaced displaced portions on said flange adapted to seat in said spaced recesses, the end of the tube being turned over the edge of the other side of the opening to lock the parts t0- gether.

Ll. In a cop holder, a ratchet base, a central tube secured thereto, an outer sleeve secured to said central tube, and spaced longitudinally disposed resilient strips on said outer sleeve in arched relation to said central tube, said strips having port-ions dis *c placed circumferentially with respect to the tube.

5.,In a cop holder, a ratchet base, a central tube secured thereto, an outer sleeve secured to said central tube, and spaced longitudinally disposed resilient strips on said outer sleeve in arched relation to-said central tube, said members being substantially U-shaped in transverse cross section with the rounded base extending outwardly. 6. An outer sleeve for a cop holder or the like comprising cylindrical end portions, spaced U-shaped connecting strips integral therewith, said strips being arcuately displaced bothaxially andr cireumferentially.

In testimony whereof I affix my signature.
